Tire tread



FIG. 1 is a perspective view of a tire tread showing my new tread design, it being understood that the tread pattern, as shown in FIG. 1, is repeated over the outer circumference of the tire and the tread shoulder, and the opposite side view being a mirror image thereof; and,

FIG. 2 is an enlarged fragmentary plan view of a portion of the tread of my new tread design as shown in FIG. 1.

The broken line disclosure of a tire bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
